Breakaway iceberg is a total area of nearly 6 thousand kilometers.
In 2017, from Antarctica to the Arctic ocean off the iceberg A68 weight of 1 trillion tons, the size of the state of Delaware in the USA – 5 thousand 800 square kilometers.
According to scientists, a crack in the glacier was discovered in 2014.
Says Professor Stef Lermitt from the University of Delft in the Netherlands, usually chunks of ice masses remain in place.
But in this case we are talking about a drifting iceberg. Experts fear that the iceberg will break up into smaller pieces and satellite photos of his path impossible to trace.
The Professor compared the location of the iceberg with the previously made. The photo clearly shows that the piece of ice broke off from the ice mass
While Dr. Natalie Robinson, a marine physicist from the National research Institute of water and atmosphere New Zealand, believes that such event for the ice mass in Antarctica is not new or unusual.
But Professor Nancy Bertler from the Antarctic research centre of Victoria University of Wellington believes that the reason for crushing ice massifs of the Antarctic were: global warming and the hole in the ozone layer. In her opinion, to such climate changes of the ice massifs of the Antarctic for over 10,000 years and remained stable.
At the moment the satellite Deimos-1 continues the monitoring of the drift of the iceberg A68 and another Sputnik – like Deimos-2 – removes the enlarged image with very high resolution.
Dr. Hogg, researcher in the ESA centre for polar observation and modelling at Leeds, said: “We see that the remaining cracks continue to grow in the direction of the object under the name of Bawden Ice Rise, which supports the integrity of the ice shelf”. According to the scientist, from the specified array of ice can break away and other icebergs.
